March 23, according to foreign media reports, British scientists have developed a wearable brain scanner, the scanner has to be put on, the patient can still be free to head activities。
In a complex disease brain tumor, epilepsy, schizophrenia, doctors usually need to use observed in patients with brain activity to diagnose the disease, and magnetoencephalography (MEG, referred to as MEG) has become a newly detected brain activity technique, the neural network can be plotted, and the human body without trauma。
However, Brooke (MattBrookes) at the University of Nottingham points out, is still inadequate MEG, as the system is very cumbersome, the position sensor is fixed in a universal helmet does not move in。
Once the position of the sensor head relative to a slight change, the quality of the resulting data will be decreased significantly, even five millimeters are also not moving。
For this reason, scientists have been working to improve the system。 Recently, they finally developed a brain scanner prototype of a wearable。 The helmet made by the 3D printing, only 905 g weight。
